Participants

Reaction Steps

Sodium bis(trimethylsilyl)amide (36.8 mL, 1.0M in THF, 36.8 mmol) was added slowly to a solution of 4-tolyl isothiocyanate (2.5 g, 16.75 mmol) in THF (30 mL) and acetonitrile (5 mL) at −78° C. The mixture was warmed to r.t. over 1 h. N,N-Dimethyluracil (2.35 g, 16.75 mmol) and EtOH (20 mL) were added and the mixture heated at reflux for 4 h. Volatiles were removed in vacuo and the residue was dissolved in EtOH (6 mL). Et2O (˜60 mL) was added slowly to produce a fine, off-white solid. The suspension was cooled to 0° C. and the solid filtered off, washed with Et2O and dried to give the title compound as an off-white solid (1.7 g, 39%). δH (DMSO-d6) 7.15-7.12 (3H, m), 6.80-6.77 (2H, m), 5.60 (1H, d, J 9.1 Hz), 2.30 (3H, s).
